ABSTRACT

In this study, with the object of alluvial plain in the whole area (hereinafter referred as the research area) of Gunsu-ri, Buyeo Chungnam Province we carried out facies analysis and stratigraphic analysis of the alluvium based on field work and preceding study materials to investigate the sedimentary structure of the alluvium in the research area. The result is like the following. ① It was confirmed that various alluvial geographical features formed over the Last Interglacial~Holocene are revealed on the current ground or buried under the ground in the research area. ② It was confirmed that clay layer(brown and yellow) and organic clay layer(grayish blue~charcoal gray) are deposited in the buried small valley formed dissected terrace gravel responding to the period of low sea level of the Last Glacial in the river terrace(formed in the Last Interglacial). ③ In the point bar(formed in Holocene), buried alluvial island, natural levee and back marsh were found. ④ Especially in terms of sequence of strata, the above-mentioned organic clay layer is naturally connected with ‘Baekje period paddy field layer’ buried in the research area. It means it is highly likely that the back marsh of Geumgang River distributed in the research area were partially used as farmland in Baekje period.
